What's kind of funny is that lots of people talk about playing the Martingale, which is dumb, but no one ever talks about playing the reverse Martingale - which is also dumb and losing, but at least has what I'd argue is a more favorable outcome distribution. Basically, with a reverse Martingale you'll usually lose a moderate amount (which, I mean, is what you'd expect since...casino) but occasionally win a larger amount when you hit your winning threshold and get, say, 6 positive results in a row.
